Lost a front cover screw of A700 reg, where to buy?

[uglyduckling]

After cleaning my reg's (A700) diaphragm, i unfortunately lost a screw (torx T10) for the front cover. I have emailed Scubapro and I was told to contact authorised dealers in my country. Unfortunately most of them are are not replying, so maybe there's a shop someone can recommend I could buy a set of screws and have them ship here in New Zealand?

Thanks in advance for your help!

If some Scubapro guru can ID the thread type that would be a big start...

Otherwise if you remove one of the others and ID the thread type (for Scubapro most likely US Imperial #6-32 x 1/2" or similar) and length (ideally should have a vernier and thread gauge for positive ID)

Button head internal T10 in 316 stainless for marine use.
Once ID'd they are readily available in bulk online... could upgrade 'em all to Ti while you are at it

It's actually a flat head (the chrome plated one which i have). Anyway, thanks and i'll try your suggestion (ID the thread and find elsewhere) though I would prefer to buy from an authorised distributor to be sure.

Aha one of these?

T10 internal countersunk head?

Well, well... I stand corrected!

Scubapro has changed fasteners to the Metric system on the A700.
Part No 01103700 Screw M3

All you need to do is measure one of the old screws for length.
Hard to see in the pic but CSK screw heads come in flat or raised styles.
